GEORGE J. GALBRAITH, OF BOSTON, MASSACHUSETTS, ASSIGNOR TO THE ELECTRIC GAS LIGHTING COMPANY, OF SAME PLACE.

ELECTRIC HAND-LIGHTING GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 652,430, dated June 26, 1900.

Application filed August 24:, 1899- Serial No. 728,268. (No model.)

To aZZ whom it may concern:

Be it known that l, GEORGE J. GALBRAI'IH, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Electric Hand-Lightin g Gas- Burners, of which the following is a specification.

My invention relates to that varietyof said [O apparatus commonly known as pulldown burners, in which a lever-arm moves a springelectrode into contact with a fixed electrode at the burner-tip and at the same time turns the gas-cock so that the gas is ignited by an electric spark made by the making and breaking of said electrodes, while the reversed motion of the lever-arm turns off the gas. Under my invention no contact of the electrodes occurs on turning off the gas. My invention will be understood clearly from the accompanying drawings, in which- Figurel is a front view showing the gas turned off. Fig. 2 is a front view showing the gas turned on. Fig. 3 is a side view. Fig. 4

2 5 is a detail of the electrode-carrying arm, and Fig. 5 is a detail of the operating lever-arm.

A is a burner-pillar having the fixed electrode a supported upon the insulated collar a, near to the lava tip a 0 B is the oscillating gas-cock.

C is an electrode carrying arm rigidly mounted upon the spindle of said gas-cock, having the angle C, with the perforation 1 and the perforated support 0 c is a pin passing through said support 0 and perforation 1 and is surrounded by the coiled spring 0', terminating in the wipingelectrode point 0 D is an operating-lever pivoted at 5 upon 0 said electrode-carrying arin C and constructed with the orifice cl, larger than the spindle of said gas-cock, over which it plays, and has also attached the operating-wire E. A coiled over-the-center spring is attached to a stand .5 ard 6, projecting from the burner and also to an arm 4 upon the electrodecarrying arm C, to retain said arm in place. The pivot 5, passing through the hole 2 in C, serves as a fulcrum for the lever D. The function of the lever D is twofold-to elevate the electrode pin 0 and also to operate thegas-cock.

The method of operation of my apparatus will be plain. The gas being turned off, as in the apparatus shown in Fig. 1, pulling down upon the operating-wire will cause the lever- 5 5 arm D to act as a lever fulcrumed at 5 by its slot cl bearing against the spindle of the gascook, and the result of the force applied to the dependent wire will be to bring the ap paratus into the position shown in Fig. 2, in

the course of doing which the lever D will push the pin 0 in the coiled spring 0 upward,

so as to bring the wiping-electrode 0 into wiping contact with the fixed electrode a to make the spark to light the gas emitted by oscillation of the gas-cock by the lever-arm. Upon pushing up upon the operating-wire to return the apparatus to the position shown in Fig. 1 the lever-arm will not strike the pin 0, which will not be elevated, and so there will be no contact made between the two electrodes in turning off the gas.

Having described my apparatus, what I claim is-- 1. In an electric hand-lighting gas-burner, the combination with a burner-pillar provided with a fixed electrode, of an oscillating cock; an electrode-carrying arm rigidly attached to the spindle of said gas-cock and formed as described; a movable pin c carried by said electrode-carrying arm; a coiled spring 0 surrounding said pin 0 and termi nating in 0 an operating-lever fulcrumed upon said electrode-carrying arm and constructed with a slot (1 playing about the gas- 8 5 cock spindle, said lever operating the pin 0; and a spring, one end attached to said burner pillar and the other to the electrode-carry ing arm; all substantially as described and shown.

2. In an electric hand-lighting gas-burner having a fixed electrode, in combination with an oscillating gas-cock, the e1ectrode-carry ing arm C constructed with the bend or a11- gle C, the support 0 and the catch 4; pin 0, 5 spring electrode c 0 and an operating-lever D properly fulcrumed on said electrode-carry ing arm; all substantially as described.

3. In an electric hand-lighting gas-burner or an open position; all substantially as de- 10 having a fixed electrode, in combination With scribed.
